COLOSTOMY PAD Filed Jan. 22, 1956 Patented June 2, 1936 UNITED STATES PATENT OFFICE 3 Claims.

-My invention relatesl to an improvement in colostomy pads, the object being to produce at a relatively low cost for manufacture, a pad of superior convenience and eifectiveness, as well as long life.

With these ends in View, my invention consists in a colostomy pad comprising a concavoconvex body of sponge rubber having a thin, impermeable, flexible skin or film covering its inner face and a supporting backing applied to its outer face.

My invention further consists in a colostomy pad comprising a concavo-convex body of sponge rubber having a thin, impermeable, flexible skin covering its inner face and having a supporting backing applied to its outer face, the edges of the said skin extending outwardly Iover the edges of the said concavo-conveX sponge-rubber body and joining the edges of the said backing to seal in the said body.

My invention further consists in a colostomy pad characterized as above and having certain details of construction as will hereinafter be described and pointed out in the claims.

In the accompanying drawing:

Fig. 1 shows my improved pad applied to a figure;

Fig. 2 is a view in front elevation of an abdominal belt shown as open for the removal or introduction .of the pad, which is illustrated as in place, but, for convenience of illustration, shown without any paper or other napkin;

Fig. 3 is a View in elevation of the belt as extended;

Fig. 4 is a detached'view of one form which my improved pad may assume; and

Fig. 5 is a view thereof in transverse section on the line 5-5 of Fig. 4.

My improved pad 9 as herein shown consists of a concavo-oonveX oval body II! of sponge rubber of suicient thickness so that when compressed by the pressure of the expelled fecal matter, it creates what may be termed a temporary fecalpocket, which is indicated by the broken line II,

the edges of the said body being, as shown, ta-

pered or thinned. The inner face of the said body, including its tapered or thinned edges, is entirely covered by a thin, impermeable, exible rubber skin I2, while its outer face is substantially lcovered by a relatively-rigid, impermeable, hard-rubber backing I3, the edges of which are tapered from the center outward in all directions and fall just short of the tapered edges of the concavo-convex sponge-rubber body I0. The tapered edges of the body IIJ are also covered by the skin I4, which projects beyond them and is turned outward and over to meet the tapered edges of the hard-rubber backing I3 so that the spongerubber body is everywhere enclosed and sealed in and so protected against its penetration by any fluids. The particular shape or outline of the pad as a unit may be varied according to circumstances.

In use, a relatively-large napkin or towel of soft paper, such as crepe paper, or cloth, or equivalent material 22 is placed over the colostomy and against the persons skin. 'Ihe pad is then placed directly over the towel and hence over the colostomy and held firmly in place by pressure applied to the outer face of its hardrubber outer backing by means of a suitable abdominal belt, which securely prevents it from moving in either direction after having been applied. As. shown in Fig. l, the towel 22 extends above and below the edges of the belt. The belt itself may be of any approved construction. As shown, it consists of a relatively-wide two-part band I5 stilfened with bones I6 and provided with snap-fasteners I'I of the .ordinary button type, located at its respective ends. The two halfsections of the band are united by lacings I8 providing for the adjustability of the belt. The ends of the lacings I8 are secured in the usual manner to belt-straps I9 and 20, one of which is provided with an ordinary buckle 2l. To open the belt, the strap is unbuckledand the fastenings I'I are pulled apart for the introduction or removal of the pad and towel. The edges of the pad are thus pressed rmly against the body of the wearer and held in place under the required pressure by means of tightening the belt in the usual manner. When the belt is tightened as described, the thinned edges of the pad are so firmly pressed against the towel and hence upon the skin of the wearer that no air or gas or uids can escape.

In the operation of the belt, when fecal matter is ejected against the towel 22 covering the skin I2 of the concavo-convex sponge body I0, the same is compressed as indicated by the broken line II to form a fecal-pocket, which is lined, as it were, by the towel which receives the fecal matter. To remove the pad, it is only necessary to loosen and separate the belt-straps I9 and 20, after which the button-fasteners are disengaged, as shown in Fig. 2, sufliciently to permit the removal, by its gathered edges, of the towel containing the fecal matter, in most cases without so much as staining the pad proper. now cleansed if necessary, another towel is placed The skin is `in position and the pad replaced and anchored in position by the belt, as described.

My improved pad, on account of its peculiar construction, is very light and convenient to handle and its adaptation to form in itself a fecal pocket under the pressure of fecal matter makes it very ecient as a surgical bandage.

I have described the supporting backing yof the sponge-rubber body of the pad as made of hard rubber or equivalent material. Thus, I may nd it feasible to use light metal or pressed paper or any impermeable composition of suiicient rigidity to hold the sponge-rubber body in shape, in place of a hard-rubber backing.

I claim:

1. A colostomy pad comprising a concavoconvex body of sponge rubber having a thin; impermeable, flexible skin or lm vcovering its inner face and an impermeable supporting backing applied to its outer face.

2. A colostomy pad comprising a concaveconvex body of sponge rubber having a thin, im* permeable, flexible skin or film covering its inner face and an impermeable supporting backing covering its outer face, the projecting edges of the said skin being lapped over the outer edges of the sponge-rubber body to prevent the access of air or of liquids thereinto.

3. A colostomy pad comprising a concavoconvex body of sponge rubber, the edges of which are tapered or thinned, a thin impermeable skin or film covering the innerface of said concavoconvex body, and a hard-rubber backing applied to the outer face of the said body for supporting the same and having its edges thinned and stopped short of the tapered edges of the body. the said skin being lapped outwardly over the tapered'edges 'of the sponge body and joined to the tapered edges of the rubber backing so as to exclude air or liquids from the said body.
